Where is the bank two sensor on a Chevy silverado 1500?

The location of the bank 2 oxygen sensor (O2 sensor) on a Chevy Silverado 1500 depends on the year and engine. There's no single answer. Bank 2 is always on the passenger side of the engine. However, the *exact* location on that side varies – it could be upstream (before the catalytic converter) or downstream (after).

To find it, you need to:

1. Identify your engine: Check your vehicle's documentation or the sticker on the driver's side doorjamb. Knowing the engine (e.g., 5.3L V8, 4.3L V6) is crucial.

2. Consult a repair manual: A repair manual specific to your year and model Silverado will have diagrams showing the exact location of all sensors, including the bank 2 O2 sensors. Chilton, Haynes, and factory service manuals are good options.

3. Use an online parts catalog: Websites like AutoZone, Advance Auto Parts, or Napa Auto Parts allow you to search by your vehicle's year, make, model, and engine. The diagrams for oxygen sensors often show their location.

Without the specific year and engine of your Silverado, I cannot give you a precise location. Trying to locate it without the proper information risks damaging other parts. Using a repair manual or online parts catalog is highly recommended.
